I am very surprised that pencils are "legal" to use in the
hospital histo labs.  For years and years we used china markers
for block identification......until the FDA nailed us.  We have
to have PERMANENT markers that will not rub off or possibly
scratch off or able to be changed by any other means. I am
shocked that with surgical specimens this is not yet an issue. 
If I have to have surgical path done, I sure don't want any
chance of a mix-up!
